| 摘 要： | 本研究为加强对胶东半岛干旱的研究，为地方制定抗旱减灾政策提供参考，减轻干旱、旱灾带来的影响，根据胶东半岛24个气象观测站1971—2012年的气温及降水资料，对该区域的气温和降水变化趋势进行统计分析，然后利用德玛顿干旱指数对胶东半岛的干旱进行评估。研究发现，胶东半岛的年及四季的平均气温呈明显上升趋势；降水量变化不明显，春季和夏季呈增加趋势，秋季和冬季呈减少趋势，增加和减少的幅度相当。以此导致了未来中旱发生次数将增加，重旱发生次数将减少。德玛顿干旱指数在一定程度上能够较好地描述胶东半岛的干旱，但对某些情况把握不佳。

Drought in Jiaodong Peninsula Based on De Martonne Aridity Index |
| |
| Abstract: | This paper aims to enhance the research on drought in Jiaodong Peninsula, to provide reference for local government to establish the policy of drought resistance and disaster reduction, and to reduce drought impact. According to analysis of temperature and precipitation data from 1971 to 2012 at 24 meteorological stations in Jiaodong Peninsula, the variation trends of meteorological factors are statistically analyzed and drought in Jiaodong Peninsula is evaluated by analyzing the De Martonne Aridity Index. The results show that the annual and the seasonal average temperatures are rising significantly, while precipitation variation is not significant, which shows an increase trend in spring and summer and a decrease trend in autumn and winter. The cases above cause that the number of occurrences of the middle drought will increase while that of the heavy drought will reduce. The De Martonne Aridity Index can be used to describe the drought in Jiaodong Peninsula in a certain extent, but it is not applicable in some cases. |
